The Design And Implemetation Of N-tier ERP System Based On EAServer

Today, with the coming of China Market Economy Reforming and the participating into WTO, all companies are facing to a lot of opportunities and challenges. The business competition becomes more intensive. Therefore, the company has to find some new methods and conceptions to resolve the problems of competition and management.

The application systems and subsystems are divided to logical components and data access components. The system's compatibility and scalability are supported by EAServer components integrated planform and Object Oriented development.3, Achieve the deployment of Enterprise Application Server system and SQL Server database cluster system. Provide high performance, fault tolerance, load balance, and enterprise security.The detail jobs in this project include investigating the history and recent status of ERP concept, researching architecture of popular ERP systems, designing OZARK ERP sytem architecture, designing database structure, implementing interfaces and important classes/components, and designing and implementing business logic structure and workflow.
